Patterns and functions – identifying and creating patterns
Look around you, can you see a pattern? A pattern is an arrangement of shapes,
numbers or colours formed according to a rule. Patterns are everywhere, you
can find them in nature, art, music and even in dance! Patterns can grow or
repeat depending on the rule
Recognising number patterns is an important part of feeling confident in
maths. In this topic we will look at different number patterns but first let’s look
at shape patterns.

Look at these repeating shape patterns. Draw the last two shapes:

Patterns and functions – predicting repeating patterns
When we use number patterns in tables, it can help us to predict what comes
next. Look at the table below and how we can use it to predict the total number
of sweets needed for any number of children at a party.
This table shows us that 1 sweet bag contains 8 sweets and 2 bags contain 16
sweets. We can see that the rule for the pattern is to multiply the top row by 8
to get the bottom row each time.

To find out how many sweets are in 10 bags, we don’t need to extend the table,
we can just apply the rule.
10 &times; 8 = 80. So, 10 bags contain 80 sweets. This helps us plan how many
sweets are needed for a party.

What
to do
apply
This is a game for 2 players. You will need some
transparent counters each in 2 different colours and
2 dice.
copy
Player 1 rolls 2 dice. The first die shows the starting number and
the second die shows the skip counting pattern. Player 1 writes
down the first 4 numbers of their sequence.
For example, if Player 1 rolls a 2 and a 6, the starting number is 2
and the rule is + 6. So Player 1 writes 2, 8, 14, 20 and chooses one
of these numbers to cover with their counter.
Player 2 has their turn, following the same steps as above. They
choose one number to cover with their counter. If the number is
already covered, they can’t put down a counter. The winner is the
first player to have their counters in a group of 4 (2 &times; 2).

Equations and equivalence – understanding equivalence
Look at these balanced scales.
On one side there is the sum 4 + 3 and
on the other side there is a total of
7 triangles. This makes sense because it
shows the equation 4 + 3 = 7.
4 + 3
Equation is another word for a sum. With
equations, both sides must be equal.

4 + 3 = 7
